Solvent selection is essential for industrial and analytical extraction processes to ensure environmental safety and neutrality. Nevertheless, toxic and hazardous solvents are often used, due to their cost-effectiveness and ready availability. In green chemistry, alternative solvents such as supramolecular deep eutectic solvents are gaining attention due to their superior performance compared with traditional non-green solvents in certain applications. Here we review the use of supramolecular deep eutectic solvents as a green solvent for analytical and industrial liquid–liquid extraction processes, with focus on physicochemical properties, extraction conditions, the capacity factor, the enrichment factor, fuel desulfurization, extraction of biological active compounds, lignin valorization, and sample preparation.

溶剂选择对于工业和分析萃取过程至关重要，以确保环境安全和中性。然而，由于有毒和有害溶剂的成本效益和现成的可用性，经常使用它们。在绿色化学中，替代溶剂（如超分子低共熔溶剂）由于在某些应用中与传统的非绿色溶剂相比性能优越而受到关注。在这里，我们回顾了超分子共熔溶剂作为分析和工业液-液萃取过程的绿色溶剂的使用，重点介绍了物理化学性质、提取条件、容量因子、富集因子、燃料脱硫、生物活性化合物的提取、木质素增值和样品制备。
